Quinazolinone derivatives as suitable mitigator for corrosion inhibition of carbon steel in hydrochloric acid environment.

), rise in % inhibition by raising the temperature and the lowering in activation energy (E*) in presence of inhibitors than in its absence. These chemical compounds function as mixed-type inhibitors, according to PDP studies. Surface characterization of the inhibited CS using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and Fourier transform infrared spectroscopy (FTIR) demonstrated significant improvement in surface morphology. The collective results from all employed techniques exhibited strong agreement, validating the inhibitory performance of the studied compounds.
